STUDY CONCERNING THE INFLUENCE OF CERTAIN HYDROPHILIC AUXILIARIES ON THE PROPERTIES OF THE PLASTICIZED POLYVINYL CHLORIDE POROUS FILMS PART II-HYGIENIC PROPERTIES

The purpose of this paper was to obtain certain PVC films with improved hygienic properties, with applications both in the artificial leather industry and in Pentair MagicStream Laminar Parts other domains.This was done by introducing certain hydrophilic auxiliaries with free chemical functions into the chemical structure of the PVC films, such as:

Whilst attention has been focussed on combating priority weeds we have neglected to obtain an overall picture of our weed flora.To rectify the position a National Weed List has been compiled, the weeds have been classified and an analysis made of the weed flora.Aspects covered in this paper are: major taxa, exotic Pentair MagicStream Laminar Parts

The recent catastrophic seismic hazards have emphasized the crucial need for retrofitting structures built before adopting modern seismic building codes.This study presents a life-cycle sustainability assessment framework to evaluate various seismic retrofit strategies for reinforced concrete (RC) frame structures in earthquake-prone regions.The fr
